SPECIFICATION forming part of Letters Patent No. 745,083, dated November 24, 1908.

Application filed August 18. 1908. fierial No. 169,920. (No model.)

To 6066 wlwm it nut/y concern:

Be it known that I, HENRY H. STUSSY, a citizen of the United States, and a resident of Beresford, in the county of Union and State of South Dakota, have invented a new and Improved OreanrSe parator, of which the followingis a full, clear, and exact description.

This invention relates to'improvements in cream-separators of the centrifugal type, an object being to provide a machine of this character that will be simple in construction, that may be readily cleaned, and that may be easily operated.

I will describe a cream-separator embodying myinvention and then pointout the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of a creamseparator embodying my invention. Fig. 2 is an elevation, partly in section, of a fixed cylinder employed. Fig. 3 is an elevation, partly in section, of a rotary cylinder employed. Fig. 4 is a plan view of the separator. Fig. 5 is a cross-section thereof on the line 5 5 of Fig. 1; and Fig. 6 is a sectional detail, hereinafter more particularly described.

The separator comprises a casing 1, supported on a platform or bottom wall 2, and arranged Within this casing is a fixed cylinder 3, having on its inner side a spirally-disposed continuous rib 4, which continues around the dome-shaped top 5 of the cylinder. Supported by the top 5 and communicating with the interior of the cylinder is a receptacle 6 for the cream which discharges through an opening 7 in a tube 8, arranged transversely in said receptacle 6, and this opening 7 is controlled or adjusted for the outlet of cream by means of a screw-valve 9. From the tube 8 the cream discharges into a casing 10, surrounding the receptacle 6 and having a removable cover 11 and also having a discharge-- pipe 12 for the cream.

M0unted to rotate in the cylinder 3 is a cylinder 13, having a spirally-disposed continuous rib 14, this spiral being the reverse of the spiral 4. The cylinder 13 has a bowl-shaped closure 15 at its upper end, provided with perforations 16, through which the skimmed milk may pass to the interior of the cylinder, where it is discharged through a pipe 17, leading through the bottom or platform 2.- The cylinder 13 is removably placed on a shaft 18, which extends downward through a stuffing-box or hearing 19 in the bottom or platform 2. The upper end of the shaft 18 pro-- jects into a socket member 20, formed in the wall of thebowl 15, and to cause the said bowl to rotate with the shaft a rib 21 is formed in said socket member to engagein a slot formed in the upper end of the shaft. To prevent lateral movement of the cylinder relatively to the shaft, arms 22 are extended from said cylinder'to a collar 23, surrounding the shaft. The lower end of the shaft rotates in a step-bearing 24, and preferably bears on an antifriction-ball 25. On the shaft is a worm 26, engaging with a wormgear 27, on the shaft of which is a gear 28, meshing with a gear-wheel 29, carrying a pinion 30 on its shaft, the said pinion engaging with the interior gear of a driving-wheel 31, loosely mounted on a shaft 32. Rigidly connected with the shaft is adisk-like clutch member 33, having two opposite shoulders, with either one of which a pawl 34, carried by the wheel 31, may engage. This pawl is held yieldingly against the clutch member by means of a spring. By this arrangement when the shaft is rotated the wheel 31 will be carried therewith, consequently imparting rotary motion to the cylinder 13. Upon stopping the rotary motion of the shaft the gearing will continue in rotation until it finally stops, the pawl 34, of course, at this time sliding over the clutch member.

The gear mechanism is arranged in a boxing 35, the lower portion of which forms a receptacle for a lubricant 36-such, for instance, as oil-into which the worm 27 dips, and the oil will be carried by this worm and distributed to the other tooth connections. The oil may be drawn off through a valved pipe 37.

Extended outward from the upper end of the cylinder 3 is an annular flange 38, which bears upon the casing 1 and forms the bottom wall of the trough for receiving the milk and cream, the outer wall being formed by an annular upwardly-extended flange 39, while the inner Wall is formed by the dome-shaped part 5 of the cylinder. From this receptacle or receiver for the milk and cream, tubes 40 extend downward along the outer side of the ceiver for milk and cream at the upper end cylinder 3 and communicate with the interior thereof near the bottom.

Supported by the boxing is a tank 41 for the milk and cream which is discharged to the machine through a spigot 42, the valve of which may have any suitable means for regulating the outflow.

Within the bowl 15 are secured stems 42, one of which is shown in Figs. 1 and 3, the purpose of which is to keep the milk and cream in motion as the bowl is rotated and throw the cream up toward the cream-dome 6.

In the operation the milk and cream from the tank 41 pass down through the tubes and into the space between the cylinders 3 and 13. As. the inner cylinder is rapidly rotated, the cream by centrifugal force will be thrown outward and will travel up through the channel formed by the spiral rib 4, and thence out through the tube 12, while the milk will pass along the channel formed by the rib 14, discharge into the bowl 15, and pass through the perforations 16 into the cylinder 13, and thence out through the pipe 17.

I Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A cream-separator comprising a stationary cylinder having a continuous spiral rib in its inner side, a cylinder mounted to rotate within the first-named cylinder and having a spiral ribon its outer side extended in the reverse direction to the first-named spiral rib, and means for rotating said rotary cylinder.

2. Acream-separatorcomprisingafixed cylinder having a dome-shaped top, a spiral rib extending around the interior of said cylinder and around the inner side of the top, a reof the cylinder and having an outlet, a valve for controlling the said outlet, a casing surrounding said receiver and having an outlet, a rotary cylinder arranged in the first-named cylinder, and a spirally-disposed rib on said rotary cylinder,the spiral being in the reverse direction to that of the first-named rib.

3. A cream-separator comprising a casing, a cylinder arranged therein, a spiral rib in the interior of said cylinder, a cylinder mounted to rotate in the first-named cylinder and having a bowl-shaped upper-end closure, the said bowl having perforations leading into the cylinder, and a spiral rib on the outer side of said'rotary cylinder.

4. Acream-separatorcomprisinga fixed cylinder having outlets at its upper and lower ends, a spirally-disposed rib on the inner side of said cylinder, a dome-shaped top for said cylinder and having a spiral rib, an upwardlyextending flange surrounding said top and forming the outer wall of the receiver for milk and cream, tubes leading from said receiver and discharging into'its lower end, a cylinder mounted to rotate in the first-named cylinder, a spirally-disposed exterior rib on said rotary cylinder, a bowlshaped upperend closure for said rotary cylinder, said bowl having perforations communicating with the interior of the rotary cylinder, mechanism for rotating said cylinder, and means for agitating the contents of the bowl.

5. A cream-separator comprising a casing, a cylinder arranged in said casing, a spiral rib on the innersurt'aceof said cylinder, a domeshaped upper end for said cylinder, a spiral rib formed in the inner side of said upper end, cream-receivers having communication with the cylinder, a cylinder mounted to rotate in the first-named cylinder, a spirally-disposed rib on said rotary cylinder, and means for rotating said cylinder.

' 6. Acream-separatorcomprisingafixedcylinder, a cylinder mounted to rotate in the said boxing forming a holder for lubricant.

In testimony whereof I have signed. my name to this specification in the presence of f two subscribing witnesses.
